Abstract
(E)-4-(3-(dimethylamino) prop-1-enyl) phenol(EDP) was synthesized by the reaction of(E)-3-(4-hydroxyphenyl) acrylic acid with dimethylamine and formaldehyde through one-pot method and purified by the simple precipitation and recrystallization based on the difference of the physical and chemical properties between the product and raw materials. EDP was characterized by ESI-MS and X-ray single-crystal diffraction. Its crystal is monoclinic,space group P2(1) /c with a = 18. 060(14),b = 9. 742(8),c = 12. 710(10),α = 90°,β = 109. 829(9) °,γ = 90°,V = 2 104(3)3,Z =8,F(000) =768.0,Dc= 1. 119 mg /m3,Mr= 177. 24,λ = 0. 710 73,the final R = 0. 047 5 and wR = 0. 145 0 for 3 542 observed reflections with I 2σ(I). Through the checking for new,EDP is proved to be a new compound.
